💼 Logic Tests in Recruitment

How to prepare and succeed in your psychotechnical tests

📋 Why logic tests in recruitment?

More and more companies are integrating psychotechnical tests into their recruitment process, especially for positions requiring analytical skills, problem-solving, or decision-making.

What recruiters evaluate

  • Reasoning ability - Solve new problems
  • Speed of analysis - Process information efficiently
  • Intellectual rigor - Avoid careless mistakes
  • Stress management - Perform under pressure (timer)
  • Learning potential - Ability to acquire new skills

💡 Good to know: Logic tests measure your "fluid intelligence" - your ability to reason in the face of new problems, regardless of your knowledge. That’s why they are considered good predictors of professional performance.

Industries that use these tests

Consulting, banking/finance, IT, engineering, auditing, large companies (CAC 40), public service competitions, business and engineering schools...

🧩 Types of tests encountered

Here are the most common formats in recruitment tests:

🔢

Number sequences

Find the missing number in a series. These tests assess your ability to identify mathematical patterns.

📝 Typical example:
3, 6, 12, 24, ? → Answer: 48 (×2)
✅ Strategy:
Calculate the gaps between numbers. Test +, -, ×, ÷, powers. Look for alternating logics.
🔲

Raven's Matrices

3×3 grids with one missing box. Widely used as they are independent of culture and language.

📝 Typical format:
Grid of 9 boxes with symbols/shapes, last box = ?
✅ Strategy:
Analyze rows and columns separately. Look for: rotation, addition/removal, color change, size progression.
🔗

Verbal analogies

Identify the relationship between two terms and apply it to another pair.

📝 Typical example:
Book: Library = Painting: ? → Answer: Museum
✅ Strategy:
First identify the relationship (synonym, antonym, part/whole, cause/effect, place, function...) then apply it.
🎯

Deductive reasoning

Draw valid conclusions from given premises.

📝 Typical example:
"All managers have a blue badge. Pierre is a manager." → Pierre has a blue badge (TRUE)
✅ Strategy:
Use Venn diagrams to visualize. Watch out for traps: "all" ≠ "some", "if A then B" ≠ "if B then A".
📊

Graphical series

Identify the next element in a series of figures.

📝 Typical format:
Series of 5 figures → What is the 6th?
✅ Strategy:
Break down: shape, size, position, orientation, color/filling, number of elements. Analyze what changes from one figure to another.

📚 How to prepare effectively

1. Start early

The ideal is to start 2-3 weeks before the test. Regular training (15-20 min/day) is more effective than intensive revision the day before.

2. Identify your weaknesses

First, take a diagnostic test to identify your weak points, then focus your efforts on them.

3. Learn classic patterns

  • Sequences: Fibonacci (1,1,2,3,5,8...), powers of 2, prime numbers, perfect squares
  • Matrices: Rotation, symmetry, addition/subtraction of shapes
  • Analogies: Common relationships (part/whole, synonym, antonym, function)

4. Practice under realistic conditions

Train with a timer. Real tests are often very time-limited.

⏱️

Manage your time

Don't get stuck on a question, move on and come back if possible

Read the instructions carefully

Every second counts, but a misunderstanding is worse

🎯

Answer everything

No negative points in general, leave nothing blank

😴

Rest the night before

A good sleep significantly improves cognitive performance

🎯 D-Day: practical tips

✅ Before the test

Get a good night's sleep the night before. Have a balanced breakfast. Arrive early to avoid stress. Have all necessary materials (paper, pen, calculator if allowed).

During the test

  • First quick read - Skim through all the questions to spot the easiest ones
  • Start with what you master - Gain confidence and secure points
  • Watch the time - Keep an eye on the remaining time
  • No perfectionism - If a question stumps you, move on
  • Review if possible - Check your answers with the remaining time

Managing stress

Breathe deeply before starting. Remember that you are prepared. A little stress improves performance - it's normal and helpful.

⚠️ Mistakes to avoid

❌ Common mistakes

1. Spending too much time on a difficult question
2. Not reading the instructions all the way through
3. Looking for a logic that is too complex (often it's simple)
4. Neglecting preparation because "it's innate"
5. Training the day before instead of resting
6. Leaving questions unanswered

✅ Good reflexes

1. Train regularly in advance
2. Start with easy questions
3. Test simple solutions first
4. Use scratch paper to visualize
5. Stay calm and methodical
6. Answer all questions

🧠 Train before the big day
